It should be noted that SMART Recovery was once the Rational Recovery Self-Help Network, back when Rational Recovery used RET/REBT, and before it got rid of meetings. SMART still lists "The Small Book" as recommended reading. For those that want "old-school" Rational Recovery, with the ABCs, Cost-Benefit Analyses, and some newer things, SMART would be the place to get it.
Trimpey may now be saying that RET/REBT is insufficient for overcoming addictions, but the fact remains that he is the one primarily responsible for elevating it to the status of addiction treatment in the first place. I find RET/REBT useful as a means to personal change and growth, but too soft on addiction. Many people use it, but I needed something a little more hard core.
